🔍 Key Features & Customer-Centric Benefits
1. Precision Engineering & Stress-Free Forming
- Unmatched Accuracy: Achieves ±0.1mm dimensional tolerance and consistent curve radius-eliminating post-processing rework and reducing project timelines.
- Stress-Free molding: Synchronized stretch-bending minimizes internal stress, ensuring long-term shape stability and resistance to warping (critical for structural applications).
- High Material Utilization: 98% material yield rate reduces waste and lowers your total project cost compared to traditional bending methods.
2. Longitudinal Stretch Bending vs. Transverse Stretch Bending: What's the Difference?
It's crucial to select the right bending method for your application. Here's a quick comparison:
| Feature | Longitudinal Stretch Bending | Transverse Stretch Bending (Press Bending/Roll Bending) |
|---|---|---|
| Process | The profile is stretched lengthwise and then bent over a die. | The profile is bent by applying a localized force (pressing) or by passing through rollers. |
| Cross-Section | Excellent cross-section stability. Ideal for complex, hollow, or thin-walled profiles. | Cross-section can distort or collapse, especially on hollow profiles. |
| Precision | High precision and repeatability for large-radius bends and complex curves. | Suitable for simpler, smaller-radius bends; precision can vary. |
| Material Strength | Work-hardening during stretching can slightly increase strength. | No significant change in material properties. |
| Typical Applications | Automotive frames, rail vehicle structures, window arches, large architectural curves. | Furniture frames, handrails, simple brackets, decorative trims. |
